OSLO — Norwegian police said Monday that they planned to put more pressure on Anders Behring Breivik, the 32 year old who confessed to the July 22 bombing and shootings that killed 77 people, in an interrogation later this week.

“We don’t want to specify the time and the place, but it will be a more confrontational interrogation,” police prosecutor Pal-Fredrik Hjort Kraby said at a news conference Monday.

Hjort Kraby said that the focus of the interrogations of Breivik is on potential accomplices, the other terrorist cells that Breivik claimed exist, and on Breivik’s movements on the day of the attacks.

According to media reports, Breivik had plans to attack several other targets, including the royal castle.

Hjort Kraby declined to comment on what specific targets Breivik possibly had. “We can only say that he had targets which would be natural for a terrorist to consider,” he said.
